YARN-CLEANING DEVICE.

EPECIPICATION forming part of Letters Patent No. 353,174, dated November 23, 1886.

Application filed June 1, 1886. Serial No. 203,829. (No model.)

To aZZ whom it may concern.-

Be it known that I, JACOB A. SNYDER, a citizen of the United States, residing at Little Falls, in the county of Herkimer and State of New York, have invented a new and useful Improvement in Yarn-Cleaning Devices, of which the following is a specification.

My invention relates to yarn-cleaning devices for machines for winding bobbins; and it consists of the peculiar combination and novel construction and arrangement of the various parts for service, substantially as hereinafter fully set forth, and particularly pointed in the claims.

The objects of my present invention are, first, to provide improved means for thoroughly and effectually cleaning the yarn as it passes from the supply-cop to the windingbobbin, and which can be easily and quickly adjusted to act upon and clean different thicknesses or sizes of yarn; second, to provide the stripper or cleaning device with supplemental stripper blades,which receive the yarn when the operator fails to adjust or pass it properly between the main stripper through negligence or carelessness, as sometimeshappens; third, to provide improved guides for the yarn on its way from the cop to the stripping device, which shall insure an easy and steady movement of yarn and relieve the stripping device of a part of the strain and consequent wear.

In the accompanying drawings, which represent a part of a bobbin-winding machine embodying my invention, Figure 1 is a side elevation, parts being broken away and in section, of a portion of the machine, only sufficient parts being illustrated to insure a proper understanding of my invention. Fig. 2 is a similar view taken at right angles to Fig. 1. Fig. 3 is a detached perspective view of the stripping or cleaning device. Fig. at is a detached vertical sectional view of a part of my invention.

Referring to the drawings, in which like letters of reference denote corresponding parts in all the figures, Adesignates a portion of abobbin-frame of a bobbin-winding'machine,which has the usual'cop-table, B, and a spindle, b, on

which a cop or small bobbin, 0, is placed, so as to be free to rotate loosely thereon, and thereby permit the yarn to be freely and easily withdrawn from the cop.

The bobbin-frameis extended upwardly, as shown, and near its upper end it is provided with a bracket-lug, D, which may be formed 'or cast therewith or suitably secured to the bobbin-frame-as, for instance, by bolts or screws. This bracket-lug extends or projects outwardly from the bobbin-frame at right angles thereto, so that it lies immediately over and in line with the cop C, as shown, and the bracket-lug is provided with a chamber or compartment, d, for a purpose presently described. The extreme upper end of the bobbin-frame is provided with right-angled lugs E, which are arranged parallel with each other and overhang the bracket-lug D, and between the free ends of the lugsE is arranged agrooved guide-roller, E, which isloosely journaled on a short pin or shaft, e, that is carried by the lugs E.

A short arm or standard, F, is detachably secured to the extreme upper end of the bobbin-frame by means of a through-bolt, f, that passes through the arm and frame, as shown. This arm inclines upwardly and rearwardly, so that it is out of line with the roller E and the bobbin-frame, and the extreme upper end of the arm is bifurcated, to adapt a guide, F, to be placed between the same and j onrnaled loosely on a pin or shaft, f, thatis secured in the bifurcations of the arm,

G designates the stripper or cleaner device, which comprises two plates or blades, G G, which are arranged on or above the bracketlug D. with each other, and their adjacent side edges are arranged very close together, so as to act properly upon the yarn passing between them, and one end of each of said plates is arranged at an angle to the horizontal portion thereof, as at 9. One of the blades, G, is secured and held rigidly in place on the bracket-lug D by a binding-screw, 9, that passes through the blade and into a threaded opening in the lug, and the other blade, G is adjustable or movable laterally of the blade G, to vary the space or slot between their contiguous edges, and thus accommodate yarns of different widths. The movable or. adjustable plate G is secured on and carried by a stud, H, that is arranged within the chamber (1 of the bracket-lug, and this stud is secured on a ongitudinally-movable pin or shaft, H, which The plates G G are arranged parallel is fitted in suitable openings in side walls of the chamber of the bracket-lug. A coiled spring, I, encircles the pinor shaft, and one end of the spring bears against one of the 5 walls of the chamber d, while the other end thereof bears against the stud to force it and the plate carried thereby in one direction, the movement of the lug and plate being limited by an adjusting screw, 2', that works in a threaded opening of the bracket-lug and extends into the chamber (1 thereof, so that its inner end will come in contact with the stud.

It will be seen that by turning the'screw in one direction the lug will be forced inwardly and against the tension of the coiled spring, so that the plate carried by said lug will approach the rigid plate and thus diminish the space between the contiguous edges of the blades, and by turning the screw in the reverse direction the spring will force the stud and pin or shaft toward the screw, to draw the plate G away from the plate G and increase the space between the plates.

Each of the stripper blades or plates is provided on its outer edge with an auxiliary or supplemental blade, J, one end of which is rigidly secured to the blade G or G and which is bent or inclined, so that its free end lies a short distance from the side edges of the said blades. The function of these auxiliary blades is to catch the yarn should the operator fail to properly adjust or pass it between the stripper G after he has tied or united the end of the'yarn from the cop and the bobbin, and thereby prevent the yarn from passing to the bobbin without being cleaned of the waste thereon.

K designates the bobbin, that is rigidly secured on and carried by a revolving mandrel, 7c, and L the conical presser-roller, that is in contact with the periphery of the bobbin and rotated by frictional contact therewith. The presser-roller is loosely journaled on a pin or shaft, Z, that is carried by an arm or bracket, M, which is rigidly secured to the bobbinframe. This bracket is provided with an upwardly-inclined arm, N, that extends longitudinally of the presscr-roller, and the outer end of the arm has an angular perforated ledge or flange, a, through which a bolt, 0, passes ,to receive a supplemental vertical arm, 0, to the outer end of the inclined bracket-arm N. This supplemental arm 0 has an opening, 0, at its upper end and a slot, 0 at its lower end, and through the slot 0 passes the bolt 0 to adjustably secure the supplemental arm 0 to the inclined arm N, whereby the supplemental arm 0 can be adjusted vertically, and the mandrel K and the bobbin carried thereby can be readily moved or adjusted in line with the spindle of the machine, the outer end of the mandrel being passed through the opening 0 of the supplemental arm O,and thereby held in place.

1? designates a rock-lever for carrying the yarn back and forth over and laying it evenly and regularly on the bobbin, as is usual.

The yarn passes from the cop upwardly between the horizontal portions of the stripperblades, thence over the pulleys E and F and back through the inclined ends of the stripper-blades and the rock-lever P to the bobbin, as shown by the dotted line and arrows in Fig. l. The rollers E and Fare preferably made of porcelain, and they insure an easy draw and movement of the yarn, and the yarn passes twice through the single stripper de vice, by which it is thoroughly and effectually cleaned of the waste thereon before passing to the bobbin.

The operation ofmy invention will be readily understood from the foregoing description, taken in connection with the drawings.

I have not deemed it necessary to fully show and illustrate a bobbin-winding machine in this application; but to enable a mechanic to construct such a machine with my improvements, I will state that they are applicable to the machine shown in the patent to Campbell, dated January 18, 1876, and numbered 172,298.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a fixed bracket-lug,

an endwise-moving pin or shaft loosely fitted in the lug and free to .move longitudinally therein, a rigid stripper-plate afixed to the bracket-lug, alaterally-movable stripper-plate arranged in the same plane as the rigid stripper-plate and carried by the pin or shaft, a regulating-screw supported in the bracket-lug, to limit the movement of the shaft and deter mine the extent of the separation of the stripper-plates, and a spring bearing against the shaft, to normally hold it in contact with the regulating-screw and effect the separation of the stripper-plates, substantially as described, for the purpose set forth.

2. The combination of a fixed chambered bracket-lug, an endwise-moving shaft or pin working in the chamber of the said lug and carrying a vertical post, a rigid stripper-plate affixed to the bracket-lug above the shaft, a laterally-movable stripper-plate arranged in the same plane as the rigid plate and secured to the post of the shaft to move with the latter, a regulating-screw supported in the bracketlug and impinging upon the vertical post of the shaft and determining the extent of the separation of the stripper plates, and a coiled spring housed in the chamber of the bracketlug and encircling the shaft to bear against the post thereof, and thereby normally hold the post in contact with the regulating-screw and effect the separation of the stripper-plates, substantially as described, for the purpose set forth.

3. The combination of the bobbin -frame having the fixed bracketlug and the inclined arm at its upper end, the stripper-plates connected to the bracket-lug and arranged in the same plane and parallel with each other, and each having its free end inclined, as at g, the

having their free ends out of contact with the said stripper-blades, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in presence of two witnesses.

JACOB A. SNYDER.
